2. Machine description
2.1PURPOSE
It is used to balance the wheels of cars, vans, 4-WD, motorcycles and scooters. The wheels must weigh less than
75 kg. and, when fitted on the balancing machine, must
not interfere with any fixed part of the machine, excluding
the shaft and support adaptor.
The machine is supplied with equipment enabling the
vast majority of car wheels available on the market to be
fitted. Other wheels with special dimensions, geometry
and centring require special adaptors supplied on request.
The machine can operate only on flat non resilient floor.
To lift the machine, lever only on the base where the 3
support points are located. never, under any circustance,
apply force to other points such as the spindle, head, or
accessory shelf. It functions properly without having to
fasten it to the floor with wheels weighing up to 35 kg; for
heavier wheels, fasten it at the points indicated. Do not
mount anything other than motorbike, car or truck tyres
on the wheel balancer.

Choice with minimum static
unbalance
This program is designed to improve the quality of balancing
without any mental effort or loss of time by the operator. In
fact by using the normal commercially available weights, with
pitch of 5 in every 5 g, and by applying the two counterweights
which a conventional wheel balancer rounds to the nearest
value, there could be a residual static unbalance of up to 4
g. The damage of such approximation is emphasized by the
fact that static unbalance is cause of most of disturbances
on the vehicle. This new function, resident in the machine,
automatically indicates the optimum entity of the weights
to be applied by approximating them in an “intelligent” way
according to their position in order to minimize residual static
unbalance.
INDICATION
In the event of automatic measurement of both sides, if
the difference between the inner and outer diameters is
greater than or equal to 2”, the system sets the inner side
spring weight.
To modify this presetting, press the
button.
To display static unbalance, press the
button on the measurement screen (for ALUS static,
the inner side diameter is always considered).

5.10 ECCENTRICITY MEASUREMENT
5.10.1When and why matching
Example 2
The software associated with eccentricity measurement is
a powerful tool for determining the need to perform relative
rotation between the rim and tyre in order to reduce the eccentricity of the wheel down to acceptable limits. The principle
adopted is based on the consideration that a rim with acceptable
tolerance, mounted with an acceptable tyre, can statistically
generate a total eccentricity which is not acceptable but can
be improved by matching.
Generally speaking, rim measurement is not necessary,
accurate or useful because:
▪▪ To measure the rim it is necessary to remove the tyre.
There can by coarse errors on the outside (e.g. aluminium wheels!)
▪▪ The two rim sides can be eccentric in a very different
way. Therefore to which one to make reference? What
is the effect on the tyre mounted?
▪▪ To improve the eccentricity of a wheel, the rim should be
eccentric, to compensate the tyre. And viceversa.
▪▪ If after a rotation by 180° of a wheel, the value is still
out-of-tolerance, either the tyre or rim are too eccentric:
One of the two must be replaced!

Eccentricity of the wheel is excessive, due to an acceptable
rim or tyre but randomly placed in an “unfortunate” relative
position.
Eccentricity of the wheel cannot be compensated by the
rotation because the rim is perfect!
SOLUTION: Rotate the tyre on the rim by 180°
RESULT: wheel eccentricity 0.3 - 0.4 mm (in tolerance)
16
SOLUTION: Rotate the tyre on the rim by 180°
RESULT: no improvement is obtained.
Use of the wheel balancer
5.10.2 Presetting of tolerance on the
machine
There is no general rule concerning acceptability of an eccentricity value . As a first approximation we consider it correct
to use a threshold of 1 to 1.5 mm. The E/ECE/324 standard
prescribes 1.5 mm as max. eccentricity of a rebuilt tyre.
5.10.3 Value of static unbalance, correlated
with eccentricity
The maximum limit of the first harmonic can be set (
FIRST HARMONIC LIMIT ). When this limit is exceeded,
the wheel balancer displays the red symbol above the
button to indicate an eccentricity condition that needs to be
corrected. Press
on the unbalance measurement
screen to display the eccentricity measurement graph.:
Clear indication is given in the Measurement screen of both
the value and position of the static unbalance as well as the
eccentricity. In fact, it is interesting to check the correlations
of the two values, above all of the two positions. When the
two positions have a similar angle (± 30° one from the other),
there is a clear sign that an eccentricity is present which
can be compensated by matching.
5.10.4 Value of unbalance corresponding to
eccentricity
For user’s reference, the centrifugal force is calculated corresponding to a certain speed, compared to the force generated
by the eccentricity present on the tyre (calculated with an
approximate average elastic constant).
5.11 WHEEL ECCENTRICITY
MEASUREMENTS
The external radial eccentricity measurement is taken automatically at the end of the unbalance measurement without
having to perform specific procedures; remember to position
the sonar sensors in front of the surface to be measured
before performing a spin.
GRAPH 1 (yellow): shows the real peak-to-peak eccentricity.
GRAPH 2 (red): shows the first harmonic eccentricity.
An almost straight line graph indicates a wheel in perfect
condition.
When the wheel is moved the cursor on the graph indicates the current value with the phase referred to the
measurement sensor.
The much enlarged figures show the outer tyre surface and
axis of wheel rotation.

The following buttons are enabled:

Fig. A - shows measurement of the total Peak-to-Peak eccentricity defined as maximum radial deviation of the tyre surface.
Fig. B - shows measurement of the eccentricity of the 1st
harmonic, i.e. the eccentricity of that circle which “recopies”
the tyre shape, by averaging the local deviations of the tyre
from the round shape.
Obviously the P.P. measurement is normally greater than that
of the 1st harmonic. Tyre manufacturers normally supply two
different tolerances for the two eccentricities.
